15 minutes from Lumphini Metro Station, with amenities nearby. The location is not very central, though it is easy to get to places using train/bus which is very inexpensive.
The hostel was very clean and tidy, check in was smooth and the staff were helpful. Room and beds were clean, as was the shower room. I had a six bed dorm to myself for one of the three nights I stayed. Other floors have family rooms and single/twins.
I would happily recommend.
